JB Weld trick - SS or OEM ring?

So i was searching the forums to find out how tight the allan bolt needs to be when reinstalling an impeller on an RXP - still havent found that info

Meanwhile, i found this thread below describing the tip on filling scars in the wear ring with JB Weld. My stupid question on that is if this trick is for the SS wear rings only? because i dont recall that JB Weld sticks to platic (been forever since ive used it). I have a SS wear ring but neither type of ring is specified in the thread.

So the JB weld wont stick to the SS rings? I wonder if i should at least smooth down the scars (de-burr them) with some 400-600grit

I bet it would stick. I would use a razor blade to apply a tight wipe over the area and then go to 180 grit to smooth the rough stuff from applying and them finish with 320. Honestly a 180 finish would be smooth enough.
